If the 50mm limit is to be exceeded
In this case the owner must approach the Vehicle Safety Branch Technical Section for prior
written approval.
Where the 50mm limit is exceeded the modification may still be approved subject to a “Lane
Change Manoeuvre
Test”.
This
test must be carried out under the direction of an “Engineering Signatory” (see the
Vehicle Safety Branch Information Bulletin IB-102A Engineering Signatories) who is familiar
with the relevant Code Of Practice and the process stipulated by the Vehicle Safety Branch.
The Lane Change Manoeuvre
Test
This
test procedure is an abridged version of ISO Technical Report 3888 - Road Vehicles -
Test Procedure for a Severe Lane-Change Manoeuvre.
The intent of this testing procedure is to objectively determine the road holding ability and
handling characteristics of vehicles. It is applicable only to vehicles with GVM up to 3.5
tonne.
The procedure consists of driving a vehicle through a set track, which simulates a lanechange
manoeuvre. The vehicle is driven from its initial lane to another lane (parallel to the
initial lane), then returning to the initial lane. The length of the track sections is constant, and
the width is a function of vehicle width.
The lane-change testing must be conducted under the guidance of the Consulting Engineer
with proven experience in the automotive area.
Only skilled drivers who have automotive road testing experience should negotiate the lanechange
test track.
Upon Approval
If the lane-change manoeuvre is satisfactory and the vehicle is examined and deemed safe,
a Modification Permit will be issued for this particular modification. A copy of this Permit
should be kept in the vehicle at all times.
